Context and how to use this
Subtract direct channel costs from attributable gross revenue for a simple contribution view. Attribution is never perfect—document counting rules.
Add indirect costs if your finance team allocates marketing overhead.
Common questions
- Why ROI as percent of cost?
- It is a common shorthand: net contribution divided by spend. It can explode when spend is tiny—interpret carefully.
- Lag between spend and revenue?
- Align periods if you can; otherwise note the mismatch when presenting to partners.
